Adding debug pack.

[phpeek]

I had to edit symfony.lock by hand in order to make diff not too scary.

It would be an awesome feature to have symfony.lock sorted alphabetically as it is happening with composer.lock. :(

There's still TODO item in monolog EasyCorp\EasyLog\EasyLogHandler handler on how to solve configuring it which I think might be a blocker for introducing debug-pack here. I've solved it in a way I'm using debug-pack in my project.

Since my PR to symfony/flex has been accepted by @fabpot - symfony/flex#222 and released in https://github.com/symfony/flex/releases/tag/v1.0.44, I've decided to regenerate symfony.lock so that it is now sorted. This is gonna make reviewing symfony.lock diffs easier.

However, in light of @javiereguiluz comment in my previous PR - #716 (comment), I will close this PR if You decide to wait till unfolding *-packs dependencies in place is released.

Also composer.lock was conflicting so I've issued composer update to rehash it and updated symfony/flex and sensio/framework-extra-bundle.

@phpeek Don't wait for the unfolding of the packs. Sorted lock files are useful anyway.

@jkufner Granted. :) However, my PR introduces more "opinionated" change which is configuring easylog handler for dev's environment monolog configuration. This is currently marked to as TODO in easy-log-handler's recipe - https://github.com/symfony/recipes/blob/master/easycorp/easy-log-handler/1.0/config/packages/dev/easy_log_handler.yaml#L6 :(

@phpeek thanks for this. Don't worry about the lock file diff. About the other changes:

• Not sure about the EasyLog activation. If Symfony doesn't do that... Besides, what if we remove the Monolog dependency entirely and relay on the new and simple built-in Symfony logger?
• Abut PHPUnit, there's some active discussion on the Symfony Recipes server about that: Bump phpunit to 6.5, discourage phpunit/phpunit more recipes#293

@javiereguiluz Very good points !

I'll close this PR and submit new one with symfony.lock reordering only.

Then, I'll look into removing monolog dependency. Having plain Symfony logger in demo app is much more natural approach IMO.
